FERDINAND PREVITS, OF CLEVELAND, OHIO.

SCRAPING APPARATUS.

To all whom t may concern.'

Be it known that I, FERDINAND Pnnvrrs, a subject of the King of Hungary, residing at Cleveland, in the countywof Cuyahoga and State of Ohio, have invented a new and useful Improvement in Scraping Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention while having broad or general reference to a scraping apparatus, has, for the exemplifying purpose in hand, particular association with the inelegant art of removing hair, dirt or other undesired matter from the severed heads of say, hogs, after such have already 'been scalded.

The primary object of the conception has been to contrive a more eiicacious mode of carrying out this step in the procedure of completely dressing for the market. Secondary objects have been to devise mechanism based on my operative principle, which shall be easy of manipulation, readily cleaned, simple and hence economical of manufacture. Further considerations have been restriction in requisite, and close continuity of successive, movements of distinct operations.

The inventive conception is embodied in means which are hereinafter explained and variously combined in the claims, while the annexed drawing and particular description thereof together set forth in detail one certain means constituting my invention, the disclosed means however, being but one of various mechanical forms in which the principle of my invention may be applied.

Figure I is an elevation of an apparatus embodying my invention, showing the head of a hog in position to'be operated upon. Fig. TT, is a section on line 2-2 of Fig. I, looking downwardly and with such head removed. Fig. III is a vertical section of one detail. Fig. TV is a section on line 4-4 of Fig. l, showing this same detail in its open position.

The apparatus constructed after the manner of my invention comprises a standard -l which is provided intermediately of its ends with a shoulder 2 and on its uppermost extremity with a boss 3 provided with a hori- Zontal bearing. Somewhat below this boss and projecting in a horizontal direction to one side is a bracket 1, which supports a ver- Specication of Letters Patent.

tically extending boss 5 similarly formed with a bearing. These bearings are intended for the reception of journals constituting parts of actuating mechanism to be presently described. The standard 1 furthermore supports integrally or otherwise a second bracket 6, projecting in a direction opposite to that of the bracket 41:.` This bracket 6 has an upward extension or arm 7, and also a continuation arm 8 which projects in substantially the same lateral direction. The extremity of the arm 8 is provided with an opening 9 for the cooperative purpose to be presently manifested.

Rotatably mounted so as to rest upon the shoulder 2, is a circular operatingrtable 10, provided below with a boss 11, adapted for precise contact with such shoulder. The upper surface of the table 10 is provided with a plurality of upright prongs circumferentially arranged and in the present instance, in sets of three each. There are six such sets equally spaced with respect to each other. The middle prong 13 in each set is somewhat longer than the two adjacent prongs 12. It is upon these sets of prongs that the head of the hog is intended to be secured in such a manner that the middle prong 13 will extend well up into the snout and the two lateral prongs 12 afford a suflicient grip to preclude a rotatory movement on the part of the head. The imaginary axis of the bearing formed in the boss 5 should intersect the circumferential line of the prongs 12 and 13.

. Mounted for rotation in the bearing 3 is a stub shaft 14. This shaft projects from each extremity of such bearing, on one side for a sufficient distance to support the fixed and loose pulleys 15 and 16 respectively, and on the other side to support a beveled gear 17.

Pivotally mounted upon the upper extremity of the arm 7 and intermediately of its own ends is a lever 18. One such end is provided with an opening 19 whereby this lever may be yieldingly connected through the medium of the opening 9 and interposed tension spring 20, with the arm 8. The other end of the lever 18 is curved in a downward direction and has pivotally suspended from it a rod 21, provided on its lowermost extremityrwith any suitable type of handle 22. Lever 18 has furthermore provided intermediately of its curved end a pivotal point and, substantially, in line ythe spline shaft 24 in the direction of its own axis. The lower extremity 26 of this shaft, in its normal po-sition projects below the boss 5 and is screw threaded.Y Keyed upon the shaft 24 is another bevel gear 27, adapted to mesh with the gear 17 whereby the rotation of the latter through the medium of power transmitted to the tight pulley 15-may be transmitted to the shaft 24.

Loosely mounted upon a shoulder formed on the upper extremity of'this spline shaft 24, in a manner well known to the art, is a T, 28, and connected with this T is a. flexible hose 29. It is through this hose that a hot fluid is to be continually supplied to the hol low spline shaft for distribution upon the head and such operative parts as are adapted to come into contact therewith.

An inverted funnel shaped hood 30, comprising two halves hinged at 31 and secured Aopposite by catches 32, is fashioned interiorly at its upper constricted end with complementary screw threads 33. This permits the hood 30 in its closed position to be screwed upon the lowermost extremity of the spline shaft 24. The relative distance between the boss 5 and the table 10, and the length of the hood 30 should be such as to permit of the ready removal from the prongs, of a head which has been subjected to the scraping operation when the hood 30 is in its normal position of rest as regards its reciprocal movement. VrIhe interior surface of the hood 30 has affixed to it two complementary portions of a helically Aextending band 34. Along this band are secured in any feasible manner a suitable number of steel bristles `35 forming together in conse quence a helically extending brush. The direction ofadvance of the convolutions of the brushes 35 should be opposed to the direc tion of rotation imparted to the spline shaft 24 in order that the most eiiicacious scraping effect may be produced upon any surface with which its brushes are brought into contact.

The operation of my apparatus may now be described as follows: Assuming any number of hogs heads up to six to have been impinged upon the sets of prongs in a manner such that the snout projects in a nearly upright direction; the table l0 may be manually rotated until one or the other of such heads is directly underneath the axis of the spline shaft 24. Thereupon, while further assuming rotation from the loose tothe `fixed pulley to have been effected, a simple downward pull upon the handle 22 serves to depress the scraping hood 30 so as to inclose the head to be operated upon. Continued application of pressure serves to wedge such head more and more tightly against the interior scraping brushes of the hood 30, whereby the function of this apparatus may be satisfactorily performed. Mention should be made of the facility presented by my apparatus for cleansing those parts which are most likely to have matter adhering to them. A disassembling of the hood 30 first by disconnection from the spline shaft 24 and thereafter by opening its twol component parts, incidentally permits ready substitution of new bristles for any that might have become worn or otherwise damaged.

My invention being thus described with sufficient thoroughness, what I desire to secure by Letters Patent, and therefore claim specilically, is:

l. A scraping apparatus comprising the combination of a table, a hollow member mounted above said table and formed of complementary parts, elongated brushes attached to the interior surfaces of said parts respectively and in continuing alinement with respect to each other, said alinement being oblique relative to the axis of said member, and means for rotating the latter.

2. A scraping apparat-us comprising the combination of a frame, a table rotatably supported thereon, said table being provided on its upper surface with circumferential sets of prongs, a hollow member mounted for movement above said prongs, and an elongated brush extending diagonally upon the interior of said member.

3. A scraping apparatus comprising the combination of a frame, a table rotatably supported thereon, said table being provided on its upper surface with distinct sets of prongs circumferentially arranged, one prong of each set projecting a greater distance, a hollow member rotatably mounted above the circumferential line of said prongs, a band extending diagonally upon the interior of said member, and an elongated brush removably secured to said band.

4. A scraping apparatus comprising the combination of a. table, means for securing an object against movement thereon, a hollow member of conical formation rotatably mounted above said securing means, a helically extending brush upon the interior of said member and power means for actuating said member.

5. A scraping apparatus comprising the combination of a frame, a table supported thereon, a hollow member rotatably mounted above and having its interior surface tapering in an upward direction, an elongated brush removably secured to said surface and arranged along a helical line, and means for effecting the rotation of said member in a direction opposed to the pitch of said brush.

6. A scraping apparatus comprising the combination of a frame, a table thereon, a hollow member rotatably mounted above said table, scraping means extending di agonally upon the interior surface of said member, means for rotating said member,
